In the ever-evolving world of mountain biking, innovation is the key to unlocking new levels of performance and rider experience. The latest advancement comes from a custom-built fork that reimagines the traditional design, introducing features that set it apart from existing models.
Innovative Design and Adjustable Features
This bespoke fork draws inspiration from the Fox Podium’s inverted design, aiming to enhance both performance and adaptability. A standout feature is the off-center axle integrated into the CNC-machined aluminum dropouts. This design allows for a standard 15mm axle, deviating from the 20mm axle typically used in similar forks. The axle is secured within a keyed insert, enabling riders to adjust both the fork’s offset and axle-to-crown height. This adjustability offers a range of offsets between 44mm and 51mm, with options in between, and approximately 6mm of ride-height adjustment. Such customization allows riders to fine-tune their setup to match specific riding styles and terrain preferences.
Enhanced Stiffness and Durability
The fork’s dropouts are mounted to 34mm lower legs, with plans to upgrade to 35mm lowers in future iterations. This increase in diameter is expected to provide added stiffness and allow for larger upper tubes, which can be built lighter due to the increased strength. To protect the lowers from debris and impacts, 3D-printed guards are employed, ensuring longevity and consistent performance.
Customizable Mud Guard Integration
Addressing the common issue of mud and debris interfering with fork performance, this custom fork features a clip-in fender system. The CNC-machined crown holds a custom fender that attaches to the steerer tube and is supported by additional blocks keyed into the crown near the upper tubes’ junction. This design ensures that the fender remains securely in place, providing effective protection against mud and debris without compromising the fork’s performance.
Adaptable Damper and Air Spring System
In a move towards versatility, the fork utilizes a GRIP2 damper sourced from a Fox fork, allowing for easy replacement and customization. This approach enables riders to experiment with different dampers to find the optimal setup for their needs. On the air spring side, a simple homemade air spring is used, with plans to develop a prototype air spring that eliminates the need for volume spacers. Instead, this system offers an on-the-fly, dial-tuned air spring volume adjustment, providing riders with greater control over their suspension setup.
Conclusion
This custom fork exemplifies the spirit of innovation in mountain biking, combining elements from established designs with new features that enhance performance and rider experience. Its adjustable offset and ride-height, increased stiffness, integrated mud guard, and adaptable damper and air spring systems make it a noteworthy advancement in fork technology. While currently a prototype, it showcases the potential for future developments in suspension design, offering insights into the direction of mountain bike technology.
